Reminosys

Hard to say when they're still at the vegetative stage of growth, but the archetypal 'Blue Java' wouldn't have the degree of pink on the pseudostem like your friends here. When there's no flower, usually the best you can do is to rule in/out subgroups based on relatively stable traits like the petiolar canal. Abnormalities do sometimes happen from nutrient deficiency, disease, growing conditions, or chance mutations, so those should be kept in mind when trying to narrow it down based on observable traits. For example, sometimes pigmentation will only manifest with enough light exposure.

The likeliest explanation is that it's a 'Namwa' being sold under the name "Ice Cream", as it's rather common to see them pop up on the market with that misnomer. Plenty of mislabeled bananas are rolling around to confuse folks that don't spend inordinate amounts of time staring at them only to make embarrassingly blatant mistakes on the verdict of an ID.

If you're interested in getting a correctly identified Blue Java, best place to start looking for it is among the folks on this forum. Plenty of the old guard of the forum have grown bananas for decades now, and I would defer to their verdict if they share one different from mine.
